sample pump inlet manifold.
b. Connect tubing from the Out port on sample inlet valve 2 (S2) to port 8 on
S1.
c. Connect inlet tubing to ports 1–7 on S1 and to ports 1–8 on S2 as needed.

Plumbing Outlet Valves
Each outlet valve module includes all necessary tubing. The tubing is approximately
5' (1.5 m) in length. Determine the length of tubing you need and cut it to the
appropriate length.
To plumb the outlet valves
1. If your system has only one outlet valve:
a. Connect tubing from the Out port on the conductivity monitor or pH
monitor to the In port on the outlet valve.
